Thunderbird:Help Documentation:Keyboard Shortcuts

This table will include keyboard shortcuts for all applications covered in the app-specific areas. It will be in one file, with the visibility of columns controlled via platform-specific CSS. This is technically doable, but it may require a little extra hacking, because we unfortunately can't set display: none on table columns (the W3-specified way is visibility: collapse, with collapse being the only recognized value for the property).

This is a list of the keyboard shortcuts in Thunderbird and other applications.
